(FV), i.e., its embody be exterior panel flanging anterior-posterior length variable quantity.
In terms of vehicle body level, what flanging loss embodied is the otherness of single-piece profile Yu assembly profile, it is between the two
Bridge.In the case that accurate flanging loss can guarantee that single-piece is qualified, the profile of assembly is also qualified；Conversely, if folding
There are errors for flanging penalty values in the technique of side, and even unit price is qualified, and overall size complaint can also occur for assembly.
Currently, flanging loss is judged at scene frequently with punching mensuration, punching mensuration measures the flanging of some position
It loses in three steps: one, beating several small sircle holes on part, and with vernier caliper measurement bore edges apart from parts profile
Distance obtains numerical value A；Two, the positional distance is measured after flanging again, obtains numerical value B；Three, it is calculated by formula F V=A-B
The flanging loss amount of the point.
Punch method is a kind of intuitive quick measurement method, but, veteran flanging more demanding to measuring technique
Loss survey crew is very rare, and cost of labor is very high, also, there are deviations for the numerical value of different people measurement, and same people is twice
There is also deviations between measurement, and the error of manual measurement is larger, in addition, needing primary artificial when worker is measured using punch method
Multiple steps such as blanking, punching, flanging and measurement are completed, it is time-consuming and laborious.

Upper end sliding, until the upper end of outside plate is bonded with inner panel；
Ranging step: after the completion of undercut step, laser scanning and ranging instrument is scanned the outer profile of the bending part of outside plate,
To measure the smallest horizontal distance between laser scanning and ranging instrument and the outer profile, it is then transmit to computer；
Data processing step: computer input has between the center of the first positioning column and the right angle bending edge profile of outside plate
The distance between the center of distance A and third positioning column and laser scanning and ranging instrument D, computer get laser scanning and ranging
The smallest horizontal distance S between the outer profile of the bending part of instrument and outside plate, to calculate flanging loss late FV=A- (D-S).
Using the above scheme, blanking, the punching of outside plate and inner panel can be quickly and accurately completed by blanking punching step,
By pre- flange step, quadric flanging step and undercut step, flanging can be completed, after the completion of flanging, surveyed by laser scanning
Distance meter automatic measurement goes out the smallest horizontal distance between the outer profile of the bending part of laser scanning and ranging instrument and outside plate, thus according to
The distance of measurement calculates flanging loss late automatically, and whole process only needs worker by the mobile outside plate of working specification and inner panel, other
All by machine complete, reduce flanging loss measurement difficulty, improve the accuracy and speed of measurement.
The beneficial effects of the present invention are: worker only needs mobile by working specification when the present invention carries out flanging loss analysis
Outside plate and inner panel, other work are all automatically performed by machine, and the work difficulty of flanging loss measurement is reduced, even if one
As worker can also be completed by simple guidance, also, by standardization, the operation of mechanization, surveyed by laser scanning
The automatic acquisition range data of distance meter, and obtained a result by automatically analyzing for computer, artificial error is reduced, is improved
The precision of measurement, while also substantially increasing the speed of flanging loss late measurement.
